A power grid accident correlation reason backtracking method based on data mining and visualization

The invention relates to a power grid accident correlation reason backtracking method based on data mining and visualization, and belongs to the field of intelligent retrieval. The method comprises the following steps: S1, data mining; S2, accident event tracing retrieval; S3, displaying a tracing process in combination with a lexicon association rule; When the electric power system is in an operation state, if the system has a problem, the action information of the protection device can transmit the related information of the fault to the dispatching center; Fault information is imported intoan intelligent analysis system fault data mining algorithm is established, fault data can be analyzed, fault characteristics can be extracted, historical accident event data can be collected, mesh topology display can be carried out according to other operation information associated with the elements, and scheduling personnel can be assisted to investigate accident events, so that the system operation personnel can quic
